I have never studied in Redmond, WA, more's the pity, so cannot speak to the actual studio there.
What I can tell you is the answer to your question: "Does the Yang family do any type of fighting applications anymore?"
However, the important question to ask yourself is not "Does the Yang family do any type of fighting applications anymore?". Without question the proper question to ask yourself is: "Would I be able to learn the fighting applictions from the Yang Cheng Fu Center in Redmond, WA?".
I can answer that question for you as well, without the benefit of ever having the pleasure of attending the school.
Now, I have a question for you.
Because to do so will require you to apply yourself to the training diligently, for many years to come.
You will be required to put in the time and effort required to master the skills of the forms and push hands training before you would even be ready to understand the "fighting applications" of the art of Yang family TCC.
If you think that somehow you are going to absorb these teachings by osmosis, then you have another think coming.
It takes three years before a good teacher even knows whether he is going to teach you the "fighting applications" or not. In that time you will be required to show that you are a person worthy of learning these things.
I will not bore you with the long list of these requirements that you must demonstrate, if you are familiar with this website than you have found the yangfamilytaichi home page and can find them for yourself.
I would recommend you to go there, read the requirements for attaining the level of training you are inquiring about, then take yourself off someplace and search your soul for the answer of whether you are willing, or able, to meet those requirements.
As in all things in this life, it will be entirely up to you.
